[0030] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0031] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0032] According to an embodiment of this application, a method for recovering thermal energy is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0033] Figure 1 This is a method for recovering heat energy according to embodiments of this application, such as... Figure 1 As shown, the method includes the following steps:

[0034] Step S102: Determine the multiple components included in the target device, and obtain the first temperature and the second temperature corresponding to each of the multiple components, wherein the first temperature is lower than the second temperature;

[0035] Step S104: Based on the first temperature and the second temperature, multiple components are classified into multiple sets, wherein the first temperature and the second temperature of the target components included in each set belong to the same preset level; and the target components included in each set are connected to a corresponding heat sink.

[0036] Step S104: Generate a first control command to raise the heat generated by the radiator to a preset temperature range.

[0037] This method for recovering heat energy employs a centralized processing approach for heat sinks corresponding to equipment operating within the same temperature range. It identifies multiple components within the target equipment, obtains a first temperature and a second temperature for each component (where the first temperature is lower than the second temperature), and categorizes these components into multiple sets based on these temperatures. Within each set, the first and second temperatures of the target components belong to the same preset level. Each set contains a target component connected to a corresponding heat sink. A first control command is generated to raise the heat generated by the heat sink to the preset temperature range, effectively utilizing the heat from the target equipment. This achieves the goal of fully utilizing the heat generated by various target devices in the data center, improving energy efficiency, and reducing carbon emissions. It also solves the technical problems of low energy efficiency, high energy consumption, and high carbon emissions caused by the low heat dissipation temperatures of data center equipment in related technologies.

[0038] In some embodiments of this application, multiple sets are obtained by classifying multiple components based on a first temperature and a second temperature. This can be achieved by: obtaining a first difference in the first temperature between every two components, and determining that components with a first difference less than a preset threshold are of the same type; obtaining a second difference in the second temperature between every two components of the same type, and determining that components with a second difference less than a preset threshold, thereby dividing the multiple components into multiple sets.

[0039] For example, the primary equipment used in data centers is the server, or target device. Generally, servers are capable of responding to service requests, providing services, and ensuring service availability, depending on the services they offer. As electronic devices, servers mainly consist of a CPU, memory, hard drive, graphics processor (graphics card), motherboard, and network interface card (NIC). Currently, based on the operating temperature requirements of the main server components, the following table summarizes these requirements:

[0040]

[0041] It should be noted that the first temperature mentioned above is the normal operating temperature, and the second temperature mentioned above is the extreme operating temperature. As can be seen from the table above, the first temperature of the motherboard, CPU and graphics processor is relatively close, and the second temperature is also relatively close. Therefore, the motherboard, CPU and graphics processor can be grouped into one set and can operate stably at a higher temperature. It is easy to note that the motherboard, CPU and graphics processor mentioned above all have certain conditions for gradual heating from the first temperature to the second temperature.

[0042] In some embodiments of this application, generating a first control command to raise the heat energy generated by the radiator to a preset temperature range includes: delivering the heat energy to a gas-liquid mixing tank; separating the liquid and gaseous phase change materials stored in the gas-liquid mixing tank based on the heat energy from the radiator to obtain a gaseous material; outputting the gaseous material to a heat exchanger; and controlling the heat exchanger to perform heat exchange treatment on the gaseous material to raise the heat energy to the preset temperature range.

[0043] As an optional implementation, after controlling the heat exchanger to perform heat exchange treatment on the gaseous material to raise the heat energy to a preset temperature range, a second control command can be generated when the temperature of the heat energy is detected to have reached the preset temperature range, so as to release the heat energy generated during the above heat treatment process through the heat energy conveying pipeline.

[0044] As another optional implementation, after generating the first control command to raise the heat energy generated by the radiator to a preset temperature range, the pressure inside the first chamber of the gas-liquid mixing chamber and the pressure inside the second chamber of the working chamber connected to the gas-liquid mixing chamber can be detected at the first moment; if the pressure inside the second chamber is greater than the pressure inside the first chamber, a pressure relief command is generated to activate the pressure storage and relief interface of the working chamber, and the box-changing material of the working chamber is released into the gas-liquid mixing chamber.

[0045] Optionally, the transformer material in the working box is leaked into the gas-liquid mixing box, including: determining the working pressure adjustment value of the gas-liquid mixing box and detecting the pressure inside the third box of the working box at the second moment; obtaining the difference between the pressure inside the third box and the pressure inside the second box, and if the difference is greater than the working pressure adjustment value, generating a shutdown command at the second moment to shut down the pressure storage and release interface of the working box.

[0046] In an exemplary embodiment of this application, the real-time temperature and smoke concentration of the gas-liquid mixing box and the working box at a designated location can also be detected; if it is determined that at least one of the real-time temperature and smoke concentration is greater than a predetermined value, the fire control platform is reported; and a response command returned by the fire control platform is received to inject inert gas from the pressure storage box into the gas-liquid mixing box and the working box, and the phase change material and inert gas are released from the gas-liquid mixing box for fire extinguishing.

[0047] As another optional embodiment, the real-time temperature and smoke concentration of the gas-liquid mixing box and the working box at a designated location are detected; if it is determined that at least one of the real-time temperature and smoke concentration is greater than a predetermined value, the inert gas in the pressure storage box can be directly injected into the gas-liquid mixing box and the working box, and the phase change material and inert gas are released from the gas-liquid mixing box for fire extinguishing.

[0048] In some embodiments of this application, a heat recovery device is also provided. This heat recovery device is used to perform a heat recovery method. The heat recovery device includes: a heat exchange module, which includes: a gas-liquid mixing tank, a radiator attached to the heat dissipation point of the target device component, and a heat exchanger; wherein, the gas-liquid mixing tank is connected to the radiator, and the gas-liquid mixing tank stores a phase change material. The gas-liquid mixing tank separates the liquid and gaseous materials of the phase change material based on the heat energy from the radiator; the gas-liquid mixing tank is also connected to the heat exchanger for outputting the gaseous material to the heat exchanger, which performs heat exchange treatment on the gaseous material and outputs the liquid material. The heat energy generated during the above-mentioned heat treatment is released through a heat energy conveying pipeline; a heat exchange control module, which includes: a working chamber connected to the body of the gas-liquid mixing tank for adjusting the internal pressure of the gas-liquid mixing tank.

[0049] As an optional embodiment, the heat exchange control module further includes: a pressure tank storing inert gas for fire extinguishing, the pressure tank being connected to the working chamber, and used to release inert gas into the mixing chamber and the working chamber when the real-time temperature or smoke concentration of the gas-liquid mixing chamber and the working chamber is detected to be greater than a predetermined value, thereby releasing phase change material and inert gas from the gas-liquid mixing chamber for fire extinguishing.

[0050] As another optional embodiment, the real-time temperature and smoke concentration of the gas-liquid mixing box and the working box at a designated location are detected; if it is determined that at least one of the real-time temperature and smoke concentration is greater than a predetermined value, the inert gas in the pressure storage box can be directly injected into the gas-liquid mixing box and the working box, and the phase change material and inert gas are released from the gas-liquid mixing box for fire extinguishing.

[0052] The first determining module 20 is used to determine the multiple components included in the target device, and to obtain a first temperature and a second temperature corresponding to each of the multiple components, wherein the first temperature is less than the second temperature;

[0053] The second determining module 22 is used to classify multiple components based on a first temperature and a second temperature to obtain multiple sets, wherein the first temperature and the second temperature of the target components included in each set belong to the same preset level; and the target components included in each set are connected to a corresponding heat sink.

[0054] The generation module 24 is used to generate a first control command to raise the heat generated by the heat sink to a preset temperature range.

[0055] In this heat recovery device, a first determining module 20 is used to determine multiple components included in the target device, and obtain a first temperature and a second temperature corresponding to each component, wherein the first temperature is lower than the second temperature; a second determining module 22 is used to classify the multiple components based on the first temperature and the second temperature to obtain multiple sets, wherein the first temperature and the second temperature corresponding to the target components included in each set belong to the same preset level; each set of target components is connected to a corresponding heat sink; a generating module 24 is used to generate a first control command to raise the heat energy generated by the heat sink to a preset temperature range, thereby achieving the purpose of effectively utilizing the heat of the target device, thus realizing the technical effect of fully utilizing the heat energy generated by each target device in the data center, improving energy utilization efficiency, and reducing carbon emissions and energy consumption, thereby solving the technical problems of low energy utilization efficiency, high energy consumption, and high carbon emissions caused by the low heat dissipation temperature of each device in the data center in related technologies.

[0056] Figure 3 This is another device for recovering heat energy according to an embodiment of this application, such as... Figure 3 As shown, the device includes:

[0057] The system consists of heat exchange module B1, heat exchange control module B2, and fire protection module B3. Heat exchange module B1 is primarily responsible for achieving heat energy conversion through phase change materials. Figure 4 This is a functional module structure diagram of the heat exchange module, such as... Figure 4 As shown, the functions and roles of each module are described below:

[0058] Z01-Gas-Liquid Mixing Chamber: This module is the main storage unit and energy conversion unit for the phase change material. Its function is to connect the heat sinks of server components within the same temperature range to the gas-liquid mixing chamber via piping. The mixing chamber separates the liquid and gaseous states of the phase change material, with the separated gaseous material being sent to the heat exchanger via a gaseous output pipe. The liquid level in the gas-liquid mixing chamber should be higher than the server's installation height; typically, the mixing chamber is placed on top of the data center rack. The phase change material is generally perfluorohexanone.

[0059] Z02 - Heatsink: This module is used for heat dissipation of server equipment components. It contains phase change material input and output piping. The heatsink should be in close contact with the heat dissipation points of the component. The internal side of the heatsink's contact area contains the phase change material delivery and output piping. Ideally, the heatsink should be installed with the output piping interface facing upwards and perpendicular to the horizontal plane. If the output piping faces downwards, a downward check valve should be installed on the gas-liquid mixing tank side. The heatsink can also be an immersion-type cabinet or chassis.

[0060] Z03-Pressure relief valve (or fire extinguishing valve): This module is a safety device to ensure the pressure of the gas-liquid mixing tank and a fire extinguishing device in case of fire. The pressure relief valve should be installed at the bottom of the liquid state of the gas-liquid mixing tank.

[0061] Z04 - Heat Exchanger: This module is a heat exchange device for phase change material (PCM) and heat transfer pipelines. The input is gaseous PCM, which passes through the heat exchange pipelines and outputs liquid PCM. The PCM and the heat transfer pipelines are isolated from each other, and heat exchange is performed by a plate heat exchanger. The top of the heat exchanger has the gaseous PCM inlet and the heat transfer pipeline outlet, while the bottom has the liquid PCM outlet and the heat transfer pipeline inlet. The heat exchanger can be connected to multiple gas-liquid mixing tanks with the same temperature range.

[0062] Z10-Gas-Liquid Mixing Conveying Pipeline and Interface: This pipeline is used to connect the radiator and the gas-liquid mixing box. If the radiator output pipeline interface faces downwards, a downward check valve should be installed on the gas-liquid mixing box side.

[0063] Z11-Gas Delivery Pipeline and Interface: This pipeline is used to deliver gaseous phase change materials to the gas-liquid mixing tank and heat exchanger. The gas delivery pipeline interface is located at the top of the gas-liquid mixing tank and heat exchanger.

[0064] Z12 - Liquid Delivery Piping and Interface: This piping is used for delivering liquid phase change material to the gas-liquid mixing tank and heat exchanger. The liquid delivery piping interface is located at the bottom of the heat exchanger and below the liquid level of the phase change material in the gas-liquid mixing tank.

[0065] Z20-Heat Transfer Pipeline: This pipeline is used for heat exchanger heat exchange. If there are more than two heat exchangers, the low temperature should be set first and then the high temperature.

[0066] The B2 heat exchange control module is used to adjust the pressure inside the gas-liquid mixing tank. Figure 5 This is a structural diagram of the functional modules of the heat exchange module, as shown below. Figure 5 As shown, the functional modules are introduced below:

[0067] Z30 Control Module: This module is used for adjusting the pressure inside the gas-liquid mixing tank and for fire control. The control module can be divided into Z31 pressure storage tank, Z32 working tank, Z33 pressure regulating and communication module, and Z34 pressure storage and relief interface. The functions and roles of each module are described below:

[0068] Z31-Pressure Storage Tank: This module is an external pressure storage device for the equipment module, storing compressed inert gas, typically nitrogen. Z32-Working Chamber: This module is an internal pressure storage device for the equipment module, storing phase change material, such as perfluorohexanone, within the gas-liquid mixing chamber. Z33-Pressure Regulation and Communication Module: This module controls the pressure storage tank and its internal pressure, collects equipment information, and enables communication. This module requires pressure regulating devices and reversing valves, such as temperature regulators, pressure pumps, and pneumatic reversing valves. Z34-Pressure Storage / Relief Interface: This module serves as the interface between the pressure storage tank and external pressure inputs / outputs, and between the working chamber and the gas-liquid mixing chamber. Z13-Control Circuit: This circuit can be a wired or wireless control and communication circuit, controlling the relevant modules to execute operating commands.

[0069] The B3 fire control module is used to adjust the pressure inside the gas-liquid mixing tank. The pressure regulation and communication modules in this module are interconnected with the fire protection system and execute fire commands.

[0070] Figure 6 This is a schematic diagram of the complete process for recovering heat energy in a specific embodiment of this application, as shown below. Figure 6 As shown, it mainly includes: equipment installation and connection section, labeled A1; equipment heat exchange section, labeled A2; equipment pressure regulation section, labeled A3; and equipment fire extinguishing section, labeled A4. The specific description of the above process is as follows:

[0071] For the A1 equipment installation and connection section, based on the physical properties of gaseous and liquid states, a gravity-type heat exchange circulation system is established. The heat exchange equipment and component modules are installed and connected via piping. The height requirements are: heat exchanger > gas-liquid mixing tank > radiator; the top of the heat exchanger is the inlet for the gaseous phase change material and the outlet for the heat transfer pipeline, while the bottom is the outlet for the liquid phase change material and the inlet for the heat transfer pipeline; the heat exchanger can connect to multiple gas-liquid mixing tanks of the same temperature range; the heat exchanger should be connected to the heat transfer pipeline in the direction of heat transfer, starting with the lower temperature connection and then the higher temperature connection. The fire-fighting pressure relief valve or pressure relief pipeline outlet of the gas-liquid mixing tank should be directly above the fire-fighting area.

[0072] The heat exchange section of equipment A2 undergoes a phase change process, converting the phase change material from a liquid to a gaseous state for heat storage, and then converting it back to a liquid state for heat release. This ensures that no equipment energy consumption is involved throughout the entire heat storage and release process. Figure 7 This is the schematic diagram of the phase change reaction process of phase change materials, such as... Figure 7 As shown, this part is divided into three parts: A21, the phase change material is converted from liquid to gas by a radiator; A22, the phase change material is converted from gas to liquid by a gas-liquid mixing tank; and A23, the phase change material is converted from gas to liquid by a heat exchanger.

[0073] Specifically, in process A21, the phase change material (PCM) undergoes a liquid-to-gas phase change via a radiator. The PCM is transported from the gas-liquid mixing tank to the radiator via piping, where it completes the liquid-to-gas phase change. The gaseous PCM then returns to the gas-liquid mixing tank via piping. In process A22, the PCM undergoes gas-to-liquid separation via the gas-liquid mixing tank. The liquid and gaseous phases of the PCM are separated using gravity separation. In process A23, the PCM undergoes a gas-to-liquid phase change via a heat exchanger. The PCM is transported from the gas-liquid mixing tank to the heat exchanger, where it completes the gas-to-liquid phase change. The liquid PCM then returns to the gas-liquid mixing tank via piping. Any gaseous PCM that has not completed the liquid phase change participates in the gas-to-liquid phase change process again via the gas-liquid mixing tank.

[0074] The pressure regulating section inside the A3 equipment is used to adjust the heat exchange temperature by adjusting the internal pressure of the gas-liquid mixing tank. Figure 8 This is a schematic diagram of a process in one embodiment of this application, illustrating how adjusting the internal pressure of a gas-liquid mixing tank achieves the adjustment of the heat exchange temperature. Figure 8 As shown, this part of the process is divided into three parts: A31 pressure detection of the gas-liquid mixing chamber and the working chamber, A32 operation of the control module to increase the working pressure of the gas-liquid mixing chamber, and A33 operation of the control module to decrease the working pressure of the gas-liquid mixing chamber.

[0075] A31 Gas-liquid mixing chamber and working chamber pressure detection. Detect the internal pressure of the gas-liquid mixing chamber and working chamber: Measured working pressure of the gas-liquid mixing chamber = QY (unit: MPa); Measured static pressure of the working chamber = AZ (unit: MPa); Adjusted working pressure of the gas-liquid mixing chamber = YQY (unit: MPa); A32 Control module adds operation to adjust the working pressure of the gas-liquid mixing chamber.

[0076] Based on the measured values ​​of the operating pressure of the gas-liquid mixing chamber and the working chamber, the gas pressure inside the working chamber is adjusted through the pressure regulating and communication module, and then the operating pressure of the gas-liquid mixing chamber is increased through the pressure relief interface on the top of the working chamber. Figure 9 This is a schematic diagram of the various functional modules inside the work box, such as... Figure 9 As shown: The Z35 temperature control module controls the working pressure within the chamber by adjusting the temperature in different areas. The temperature control module can be an electrically controlled valve or a temperature regulator. The temperature control module is controlled by a pressure regulating and communication module. Specifically, it includes the following steps:

[0077] A321 Test the internal pressure and liquid level of the working chamber: Before adding the working chamber, it is necessary to test its internal pressure and the height and position of the phase change material liquid level in the working chamber. After meeting the requirements, start the working chamber working pressure increase program.

[0078] A322 Start the heating pipeline temperature control module: The pressure regulation and communication module issues an opening instruction to the heating pipeline temperature control module, and heats the liquid phase change material through the heating pipeline to vaporize it. During the heating period, the working pressure in the working box needs to be detected in real time to prevent overpressure.

[0079] A323 Open the pressure storage and relief interface at the gaseous part of the working box: When the internal working pressure of the working box is greater than that of the gas-liquid mixing box, that is, when AZ>QY, the pressure regulation and communication module issues a pressure relief instruction to the pressure storage and relief interface at the gaseous part of the working box, to discharge the pressure of the gaseous phase change material in the working box to the gas-liquid mixing box.

[0080] A324 Detect the pressure in the gas-liquid mixing box: During the pressure relief operation, the pressures in the working box and the gas-liquid mixing box need to be detected to prevent overpressure. At the same time, the liquid level height and position of the phase change material in the working box are detected.

[0081] A325 Close the pressure storage and relief interface at the gaseous part of the working box when the target pressure is reached: When the internal pressure of the gas-liquid mixing box reaches the planned adjustment pressure, that is, when QY≥YQY, the pressure regulation and communication module issues a closing instruction to the pressure storage and relief interface at the gaseous part of the working box, simultaneously stops the operation of the heating pipeline in the working box, and starts the operation of the cooling pipeline in the working box until the working pressure in the working box drops to the normal value.

[0082] A33 Operation of the control module to reduce the working pressure of the gas-liquid mixing box. According to the measured values of the operating pressure of the gas-liquid mixing box and the working pressure of the working box, the gas pressure in the working box is regulated through the pressure regulation and communication module, and then the operating pressure of the gas-liquid mixing box is reduced through the top side pressure storage and relief interface on the working box side. Specifically, it includes the following steps:

[0083] A331 Detect the internal pressure and liquid level position of the working box: Before the working box increases pressure, its internal pressure and the liquid level height and position of the phase change material in the working box need to be detected, and the working pressure increase procedure of the working box is started after the requirements are met.

[0084] A332 Start the cooling pipeline temperature control module: The pressure regulation and communication module issues an opening instruction to the heating pipeline temperature control module, and cools the gaseous phase change material through the cooling pipeline to liquefy it. During the cooling process, the working pressure in the working box needs to be detected in real time.

[0085] A333 Open the pressure storage and relief interface at the gaseous part of the working box: When the internal working pressure of the working box is less than that of the gas-liquid mixing box, that is, when AZ<QY, the pressure regulation and communication module issues a pressure storage instruction to the pressure storage and relief interface at the gaseous part of the working box, to suck the pressure of the gaseous phase change material in the gas-liquid mixing box into the working box.

[0086] A334 Pressure Detection in Gas-Liquid Mixing Tank: During pressure storage operation, the pressure in the working tank and the gas-liquid mixing tank needs to be detected. At the same time, the liquid level and position of the phase change material in the working tank should be detected.

[0087] A335 reaches target pressure and shuts off the gaseous part of the working chamber's pressure relief interface: When the internal pressure of the gas-liquid mixing chamber reaches the planned adjustment pressure, i.e., QY≦YQY, the pressure regulating and communication module sends a shutdown command to the gaseous part of the working chamber's pressure relief interface, and at the same time stops the operation of the refrigeration pipeline inside the working chamber, and detects the working pressure inside the working chamber.

[0088] Fire suppression for A4 equipment involves injecting inert gas stored in the pressure tank into the gas-liquid mixing tank, and then releasing it to the fire scene through the pressure relief port. Specifically, this includes the following steps:

[0089] A41 detects temperature and smoke at designated locations: The voltage regulation and communication module detects temperature and smoke at designated locations through detection points. If abnormal temperature or smoke is detected, it reports to the fire control platform.

[0090] A42 Fire Extinguishing Process and Temperature Control Module: With Fire Control Platform Command: Based on the command from the fire control platform, the pressure regulating and communication module injects inert gas from the pressure storage tank into the working chamber, and releases phase change material and inert gas from the gas-liquid mixing tank to extinguish the fire. Without Fire Control Command: The working pressure inside the working chamber is detected, and temperature and smoke values ​​are measured at designated points. The pressure regulating and communication module reports a fire extinguishing alarm, and simultaneously injects inert gas from the pressure storage tank into the working chamber and the gas-liquid mixing tank. The phase change material and inert gas are released from the gas-liquid mixing tank to extinguish the fire.

[0091] A43 Gas-Liquid Mixing Box Pressure Relief: When the temperature reaches the specified fire extinguishing value, the phase change material in the gas-liquid mixing box vaporizes and the pressure increases. The gas-liquid mixing box then relieves pressure and extinguishes the fire through the pressure relief interface, gas pipeline, and liquid pipeline.
